javascript - AngularJS - 刷新 ng-repeat

Question

我正在使用 ng-repeat 来显示值的集合。我的过滤器选项根据对服务器的 ajax 调用而改变。接收到过滤器参数后如何刷新 ng-repeat？

js fiddle

模板

<div>
<div data-ng-controller="myCtrl">
    <ul>
        <li data-ng-repeat="item in values | filter:filterIds()"> 
            <code>#{{item.id}}</code> Item
        </li>
    </ul>
   </div>
 </div> 
<button ng-click="loadNewFilter()"> filter now</button>

Angular

var app = angular.module('m', []);

app.controller('myCtrl', function ($scope) {
  $scope.values = [
   {id: 1},
   {id: 2},
   {id: 3},
   {id: 4},
   {id: 5},
   {id: 6}
  ];

  $scope.filter = [1,2,3,4,5,6];

  $scope.filterIds = function (ids) {
        return function (item) {
            var filter = $scope.filter;
            return filter.indexOf(item.id) !== -1;          
        }
  }

  $scope.loadNewFilter = function (){
    $scope.filter = [1,2,3];      
   }
});

您需要告诉 Angular 这些值发生了变化:

$scope.loadNewFilter = function (){
    $scope.filter = [1,2,3];      
    $scope.$apply();
}
